    I've used a Hakko model 926 for nearly 20 years now. A newer Hakko FP-
    101 has been serving me for almost 10 years. I continue to be extremely
    happy with both units and should a day come when one of them konks out
    and dies it will be another Hakko that replaces it.

    Hakko is good. Have their portable solder sucker (808) and it's pretty
    bullet proof. Except that the little plastic button that covers the cal
    pot keeps getting lost; vinyl tape works as a stand-in...

    With that in mind, if the OP is getting a new iron then this may be the
    time to get a combination unit. A vacuum-pump sucker is SO much easier
    than wick or the spring-loaded suckers.

    I second that. Best soldering iron I ever owned.

    Also, consider the DS1 desoldering gun.

    You ain't kidding when you say "a lot more". From the prices I've
    seen, 2X-4X more! For those prices, do they come with a sexy babe to
    hold the iron? ;)

    Ditto on Hakko.

    Metcal has their fanatics.

    From the Metcal owners I know, they work well but need repair often.

    I don't know what these irons are without looking up. I do know a pencil
    thin iron is the way to go. After using a pencil thin iron, those big
    things are a joke. That weller was also very high in watts.

    Many people choose a tip which is too small. When soldering doesn't
    work they crank up the temperature which ruins the tip. If the tip is
    big and the temperature right (so the flux doesn't burn) the surface
    tension will do the job for you.

    We use the cheap Metcals. In the 4 years we've been using them, no
    problems yet. Wonderful irons.

    The (older) ones I have switch the secondary so you are just seeing
    transformer losses. I don't know any reason why the primary could not be
    switched. Also, I find the report of bad cable killing solid state devices
    pretty remote. Even a lose connector will cause the unit to shut down and
    require reseting the power to get it back on again. They monitor the vswr
    for faults.

    Why not slave everything to one of the boat anchors. Don't they keep power
    supplied to the OCXO when off? At least the 856x does. They all have an in
    and an out for their clocks as far as I remember. Then you just need to keep
    power supplied to that device.

    The Rb should always be powered as it takes a long time to fully reach a
    stable equilibrium. But maybe your requirements are not that demanding.

    Next you should get one of the Trimbel Thunderbolts for < $200 and have a
    GPS traceable reference.

    Phase noise on the Rb is worse than the OCXO in the Thunderbolt, especially
    if you get one with the Trimbel OCXO.

    Stability is mostly moot for what many of us do.

    But you need a spare so you will not know what one is correct :).

    Talking to the local Meinberg rep, DGPSO wins over Rb for phase noise.
    DGPSOs are quite cheap on the used market, but you do need to set up an
    antenna. The advantage to Rb is if GPS lock is lost, it will be on
    frequency much better than a crystal.

    Most of these DGPSOs have a similar command set. You don't need the
    manufacturer's software. Just run Lady Heather.

    Yep. It seems like an overkill method to generate heat. But like I said,
    Metcal has its fans.

    I see busted Metcals in the surplus shops often. If you are in the
    valley, there is a guy who sells repaired Metcals at the DeAnza swap
    meet. Harold (blank). He comes up from Santa Barbara, so you can imagine
    he does a decent business selling repaired irons.

    I've never tried Metcal but I have experience with Weller and JBC and
    The big advantage to Hakko or Weller is I can just go to Frys and buy
    the tips.

    When I am soldering, I leave the iron on. I don't get the heat up contest.

    I just order the tips from Farnell. Next day delivery.
    Same with Ersa. The tip is held in place with a spring-hook
    contraption. Replacing the tip is a matter of seconds. I often change
    tips when working on a project. There simply is no way you can use one
    tip for all soldering jobs.
